As per client requirement, the selected VFD must support VT & CT. In siemens catalog DA 52 for the VFDs 2.2kw (6SE6440-2AD22-2BA1) 3.0kw (6SE6440-2AD23-2BA1), 4.0kw (6SE6440-2AD24-2BA1) the values for VT i.e kw ,rated input current. rated output current are not shown. I want to know what exactly it means. 1. It means , these VFDs are not supporting VT application? 2. It means , these VFDs are supporting VT application for CT rated values? 3. It means something else? Thanks & Regards
